i dont know they get rmoved or something
its not real its aconcept of what could an f1 car be today without limitation and ristrictions (google red bull f1 concept)
what i liked the most is the turbine that drains air from underneath the car so it creates a depression just like the chaparal and theorically let you take turns at +300 km/h

it had a lot to do with not only the speed of the motors but the space needed for the motors is dependent on the body style as well as new advancements in the motors along with weight and a lot of different stuff
